Popular AMH blood test fails to predict natural fertility

What the research found
Study (observational records). Flinders University researchers (Kassie, Grzeskowiak and colleagues) report in the Australian and New Zealand Journal of Obstetrics and Gynaecology that GP requests for anti-Müllerian hormone (AMH) tests among almost 1.4 million Australian women rose more than 13-fold from 2011 to 2021, nearly 20-fold among women aged 30–34, even though AMH does not predict whether a healthy woman will conceive naturally or how much reproductive time she has left. Nearly one in five results were classified as low; about one-third of those who retested later fell in the normal range. Age remains the stronger fertility signal. Educational notes, not a fertility diagnosis and not medical advice.
Evidence level: Human study. A study in people, but an association isn't proof of cause.
